WINDOW-SCREEN.

SPEGIFlCATION forming part of Letters Patent No, 794,469, dated July l1,1905.

Application filed February l0, 1905. Serial No. 245,041.

T all whom it nfl/ty concern:

Be it known that I, WILLIAM E. SHERWOOD, of Oneida, in the county ofMadison, in the State of New York,have invented new and usefulImprovements in Window Screens, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription. This invention relates to the class of win- IO dow-screensin which the frames are composed of sheet metal and slide in guides ortracks 'secured to the window-frame and at the same time areautomatically adjustable to accommodate themselves to window-frameshaving varying widths.

The main object of this invention is to produce a metallic Window screenwhich shall be simple, strong, and durable in construction, efficient inits operation, and at the same time inexpensive to manufacture.

Another object is to produce a construction which shall permit of quickand easy placement in the window-frame and removal therefrom and,furthermore, shall permit the wirez 5 cloth to be readily removed and anew piece to be applied when required.

To that end the invention consists in the novel construction andarrangement of the component parts of the window-screen hereinafterfully described, and set forth in the claims.

In the accompanying drawings, Figure 1 is a front View of my improvedWindow-screen. Figs. 2 and 3 are enlarged detailed front views of theupper corner portions of the screen, partly broken away. Fig. 4 is atransverse section on the dotted line X X in Fig. 3. Fig. 5 is avertical section on line Y Y in Fig. 2. Fig. 6 is a transverse sectionon line Z Z in 40 Fig. 2. Figs. 7 and 8 are side and end views,

respectively, of the corner-piece of the main or outer frame; and Fig. 9is a perspective view of a corner portion of the inner or secondaryframe.

Similar letters of reference indicate corresponding parts.

A A A denote the top, bottom, and one of the side members of the outeror main fratrie of the screen, and A denotes the other side memberthereof, which is adjustable, as will be shortly described. This frameis supported slidably in vertical guides or tracks B B, preferablyformed of metal and fastened to the window-frame O in the well-knownmanner. The said frame members A A A are each composed of a sheet-metalplate folded longitudinally at the center of its Width to form atubularvmarginal channel a and two inwardly-projecting parallel flangesb. These frame members are rigidly united by metallic L-shapedcorner-pieces cc, which are solid and are inserted into the ends of thechannels a a. Said corner-pieces are formed with webs CZ d, which areembraced by the flanges of the top and bottom members A of anges are inturn embraced by flanges of the side member A, and through said partspass rivets c c. 'Ihese webs d d serve as spacingblocls maintaining theiianges proper distances apart to permit the insertion of the sec- 7 0ondary or wire-cloth frame hereinafter described.

The frame member A is composed of a sheet-metal plate, foldedlongitudinally at the center of its width to form a channel f, and twoinwardly-extending parallel wide strips g g, which loosely embrace thesecondary or screen-frame proper, which will be shortly referred to. Inthe ends of the channel of said frame member A are rigidly secured 8Ometallic L-shaped corner-pieces /t L by means of rivets c' c'. Saidcorner-pieces slide in the end portions of the channels a a of the topand bottom frame members. In each of said channels ais disposed a coiledspringj, which bears at its inner end against a block or diaphragm k,rigidly secured therein and pressing with its opposite or outer endagainst the cornerpiece I, rigidly secured to the frame member A', asaforesaid. Said springs serve to force 90 the said frame member outward,and thereby maintain the frame in the guides B B. By this arrangementthe said frame member A is permitted to yield sidewise in relation tothe window, and thereby rendering the main screen-frame automaticallyadjustable to acthe frame, which 65 I the main-frame member A.

commodate itself to any variations that may l exist in the distancebetween the guides or l tracks.

By forming the aforesaid frame members or plates A A A A' in the mannerdescribed it will be observed that a double frame is produced whichpossesses great strength and rigidity. I do not,lhowever, limit myselfto the means employed for uniting the frame members as shown, as theymay be otherwise fastened. The membersZ Z Z Z of the secondary framealso consist of metallic plates which may be united by any suitablemeans, and to this frame the usual wire cloth or nettingD is securedin'any convenient manner. I prefer, however, to fold each of theseplates longitudinally upon itself at the center of its width to producea double frame and insert the marginal portions of the wire-cloththerein, so as to abut against the folded portion.. I then impart asecond fold to the plates and insert AWire-cloth, thereby firmlyclenching the wirecloth to the frame. This second fold serves to tightlystretch the wire-cloth and produce a bead, as indicated at m. Thissecondary frame is inserted with its beaded portion endwise between thefianges Z) Z of the main frame and secured removably therein by means ofbolts or screws n n. The application of the secondary frame to and itsremoval from the main frame is readily permitted by detaching The stripsof the said frame member are yielding and have their free edgesdeflected inwardly to form lips, as indicated ato 0. These lips areadapted to engage the heads of the bolts or screws and their nuts, whichconstitute stops limiting the outward movement imparted to said framemember by the aforesaid coiled springs, thereby maintaining the frameintact when removed from the guides or tracks B B. In order to detachthe frame member A', its strips are sprung apart, so as to cause thelips to disengage from the said heads and nuts of the bolts.

It will be understood thatI do not limit myself to the form of stopsshown, as other means may be employed for the purpose. The ends of thestrips of the meeting members of the secondary frame are lapped one ontoanother, and one of the strips of each member is extended beyond itscompanion l strip and folded onto the other member with the wire-cloth,thus producing an interlocking joint, as` clearly shown in Fig. 9 of thedrawings.

It will be seen that the secondary frame can be readily removed from themainframe by the removal of the bolts or screws nu. It will also beobserved that the main frame can be conveniently removed from its guidesor tracks.

0 denotes a handle which is employed for raising and lowering the screenand may be of any suitable form. I prefer, however, to

construct the same from a piece of sheet metal and fasten the same tothe lower member of the main or outer frame.
